ABSTRACT

Application of Neutron Techniques for Basic Understanding of Cellulose
Howard Wang
Department of Materials Science and Engineering, University of Maryland, College Park &Material Measurement Laboratory, NIST
Cellulose is the most abundant natural polymer on earth, widely used in everyday-life products from building construction to clothing to paper. As much effort has been devoted to developing cellulose applications through novel chemistry and nanotechnology, the scope of engineering cellulosic materials will be greatly expanded if the art of manipulating individual cellulose molecules is mastered. A better fundamental understanding of molecular interactions governing cellulose coil solutions is much needed. We have applied a variety of neutron scattering techniques to understanding the molecular solutions of cellulose in mixtures of ionic liquid and organic solvents. Structure and dynamics information from neutron measurements indicate the importance of mesoscale structures and dynamic heterogeneities. Their implications in processing molecular cellulose solution for potential applications are illustrated through fabricating thin films, fibers and nanocomposites from cellulose coil solutions.
Howard Wang Brief Bio
Dr. Wang obtained his Bachelor of Science in Physics from the Peking University in 1992 and Ph.D. in Materials Science and Engineering from the University of Pennsylvania in 1999. After postdoc research at NIST, He was an Assistant Professor at Michigan Technological Univ. an Associate Professor at SUNY Binghamton, and a Research Professor of Materials Science and Engineering at University of Maryland at College Park. He has had extensive research experience in neutron techniques applied to studying soft matter, nanotechnology, electronics and batteries, and authored or co-authored over 100 technical publications and 8 patents. Wang is member of Bohmische Physical Society, a recipient of the NSF Career Award, and a NIST-ARRA Senior Research Fellow.
